How do I find out the MAC address of my system?

To find the MAC ID / Address of a system, either:

  • Locate the MAC ID label on the back plastics of the system.
    • On integrated thin clients, the MAC ID label is located on the back, below the power input jack.
    • On thin client computers, the MAC ID label is located on the back of the system, below the certification label.

  • In MS Windows, from a command prompt, type:
    ipconfig -all

    Under the settings of the active network adapter, look for the Physical Address.
    The MAC address will be in the format
    XX-XX-XX-XX-XX-XX.
